A rancher has 200 meters of fencing available to enclose two corrals of equal area next to a river. (No fencing is required along the river) What should the dimensions be for each corral to maximize the combined area of the two corrals?
So far I have:
A(x)=(240-3x)x --> -b/2a= -240/2(-3) --> A(40)= 240(40)-3(40)^2 --> Vertex= (40,4800) -->
= 240x-3x^2 = 40 =4800 meters^2
240-3x I get 40m by 120m which gives me the dimensions for the overall area. How do I get the dimensions for each
240-3(40) individual corral to maximize the combined area?
